What is robotic welding?

On a long production run the challenge is not making a good weld: it is making the same weld hundreds of times. The robot follows the same path with the same parameters every time, so part number three hundred matches the first.

That solves two needs at once. Consistency: every unit comes out with the same bead and the same geometry. And capacity: it sustains a steady production rate on batches that would be expensive to weld by hand.

For the robot to work, the parts have to arrive accurate and correctly located. This is where cutting and forming in the same plant pays off: the preparation is part of the same process.

Materials and thicknesses for robotic welding

Metals and sheet thicknesses we work with as standard. If your industrial project needs a material that is not in the table, say so in your enquiry and our engineering office will confirm whether we can handle it.

This service works with the same materials and thicknesses as the rest of the plant. The full table is on the Sheet metal laser cutting page.

CAD file formats accepted for quoting

  • DXF
  • DWG
  • STEP / STP
  • PDF
  • STL
  • IGS / IGES
  • PNG
  • JPG

With DXF, DWG or STEP we work straight from your file geometry: no need to redraw the part, and the quote comes back sooner.

We do more than check the drawing: we advise you on nesting (how the sheet is used) so you get the lowest possible price per part before anything is cut.

How our engineering office works

If you would rather not fill in the form, send the drawing straight to cata@catagermans.com.

Confidential handling. Your drawings are only used to prepare the technical assessment and are not shared with third parties. If you need a signed non-disclosure agreement, send it over.

Why work with Catà Germans

Every process under one roof
Cutting, forming, machining, welding and finishing in the same plant. We handle the whole logistics side so you receive the parts palletised and protected at your own factory, anywhere in Catalonia and the surrounding area, on the agreed lead time.
In-house engineering office
We review the drawing before manufacturing and prepare production from CAD/CAM. If something does not add up, we ask you instead of interpreting it ourselves. And if what you have is a sketch or a question, we will help with that too: advice is part of the service.
From drawing to finished product
Some finishes, such as painting or zinc plating, are done with specialist workshops. We handle the coordination and deliver with our own fleet: a single order and a part ready to fit.
Raw material in stock
We keep sheet and tube permanently in stock, so many standard jobs can start without waiting for material.
Over 65 years of the trade
A family business founded in 1958, specialised in industrial subcontracting of metal parts. You deal directly with the people who make the part.

Frequently asked questions

01Robotic welding

What does robotic welding bring?

In a long run, the challenge is not making one good weld: it is making the same weld hundreds of times. The robot always follows the same path with the same parameters, so every unit comes out with the same bead and the same geometry.

What are the advantages for a production run?

  • Repeatability between units
  • A consistent bead across the whole run
  • A steady production rate
  • Capacity for runs that would be very costly by hand

What does the robot need to work well?

Parts that arrive accurate and well positioned. Because cutting and forming happen in the same plant, that preparation is part of the same process.

02When it pays off

From how many units does the robot pay off?

It depends on the part: geometry, set-up time and how often the order repeats all play a part. Give the expected volume in your request and we will suggest the most sensible option, robotic or manual.

Is it suitable for a one-off part?

Usually not the most efficient choice: programming does not pay off on a single part. For one-off parts and prototypes we use manual industrial welding.

Does it suit recurring orders?

Yes. Recurring orders with regular deliveries are one of the cases where the robot adds most, because the program is reused on every order.

03Robotic and manual welding

Can you combine robotic and manual welding?

Yes. In many assemblies the robot makes the repetitive beads and manual welding handles the hard-to-reach points and finishing.

Which parts is it used for?

  • Runs of welded assemblies with repetitive geometry
  • Parts where a consistent bead between units is required
  • Production where manual welding time would be the bottleneck

04Engineering office and confidentiality

Does my file need redrawing to quote for robotic welding?

No. With DXF, DWG or STEP we work directly on the geometry in your file: the part does not need redrawing and the quote comes back sooner. We work mainly with SolidWorks and AutoCAD, among other CAD and CAM tools.

Are my drawings treated confidentially?

Yes. Drawings are used only to prepare the technical assessment and are not shared with third parties. If you need a signed confidentiality agreement, you can send it to us.

What if I only have a sketch or a technical question?

Send us a dimensioned sketch or tell us what you need. Our engineering office reviews it, asks whatever it needs to and, if necessary, helps you define the part: advice is part of the service, for metalworkers and small workshops too.

05Process, lead times and delivery

What happens after I send my request?

  • Enquiry: you send the drawing, material, thickness, quantity and deadline
  • Review by our engineering office and manufacturing plan
  • Quote and confirmation, with alternatives where there are any
  • Manufacturing within the same plant
  • Inspection, packing and delivery

What lead time does a robotic welding order have?

It depends on the part, the quantity and the other processes involved. In the quote request you can choose a 24/48 h urgent service (with a surcharge), about one week, a flexible deadline or a specific date, and we confirm it with the quote.

Do you have to wait for material before starting?

For many routine orders, no. We keep sheet and tube in permanent stock, so manufacturing can start without waiting for material.

Can you deliver the parts to our factory?

Yes, with our own fleet. We prepare the load and deliver the parts palletised and protected to the agreed point. We usually serve the provinces of Tarragona and Barcelona, and look at other destinations case by case.

06Sectors and experience

Which sectors do you provide robotic welding for?

We manufacture for industrial companies in very different sectors. Some of the most common:

  • Automotive
  • Food industry (stainless steel)
  • Agricultural machinery
  • Construction
  • Structural steelwork
  • Energy
  • Street furniture

Long runs and recurring orders are common in automotive, agricultural machinery and industrial equipment. If your sector is not listed, tell us about the part and we will confirm whether we can make it.

07Quotes, files and orders

Which file formats do you accept?

We accept PDF, DXF, DWG, STEP/STP, STL, IGS/IGES and also PNG or JPG images. If you do not have a final drawing yet, send us a dimensioned sketch and we will review it all the same.

Do you make one-off parts or only production runs?

We handle one-off parts and prototypes as well as small, medium and large batches and repeat production. You can specify this in the quote request.

How quickly do you reply to an enquiry?

We send the technical response as soon as possible once we have the drawing and the part details.

Do you offer painting, zinc plating or other surface finishes?

You can include them in the order. These finishes are carried out with specialist workshops we work with regularly, but we handle the coordination and the transport: you place a single order and receive the finished part.

Can I combine several processes in one part?

Yes — that is the normal way we work. A part can go through laser cutting, bending, welding and finishing inside the same plant, under a single order and a single point of contact.
